Question

The vertical height of the climb is 790 m. The climber has a mass
of 55 kg. In the process of climbing, her body generates 4.3 × 106
J of energy via metabolic processes.

(a1) What is the algebraic expression for the climber's efficiency
e as a heat engine? Express your answer in terms of the climber's
mass m, the magnitude g of the acceleration due to gravity, the
vertical height h of the climb, and energy |QH| that the climber's
body generates via metabolic processes.
